Abstract
A heat assisted magnetic recording (HAMR) head is provided. The HAMR head is mounted in a slider having an ABS that faces a recording medium and illuminates light on the local area of the recording medium, and includes a recording unit that performs recording and a near field light emitter that illuminates near field light onto the local area of the recording medium, the near field light emitter including a light source, a waveguide, and a near field light emission (NFE) pole located between the recording unit and the waveguide, and which generates near field light that is illuminated on the recording medium using light transmitted through the waveguide.

A heat assisted magnetic recording (HAMR) head mounted in a slider having an air-bearing surface (ABS) the HAMR head comprising:
- a recording unit which performs magnetic recording;
- and
- a near field light emitter which illuminates near field light,
- wherein the near field light emitter comprises:
- a light source which is disposed on a side of the slider;
- a waveguide, which is disposed on the side of the slider where the light source is disposed, has a side disposed on the ABS, and has the recording unit disposed on an upper portion of the waveguide;
- and
- an near field light emission (NFE) pole interposed between the recording unit and the waveguide, and which generates near field light using light transmitted through the waveguide.
